Analytical plunge milling model and machining sound analysis for chatter forecast and detection

The main aim of the activity is to develop models and methods for chatter avoidance and control. An analytical plunge milling model will be presented and described, starting from the few literature existing papers. New method for cutting coefficients measurement is introduced, as well together with a more accurate configuration description and the solution algorithm in order to achieve the Stability Lobes Diagrams. The second part of this thesis is focused on developing an active control logic, to be used in a general milling application and able to recognize the milling phase (example air cutting, stable or unstable cut) based on acoustical analysis.
